摘要:
A server apparatus for establishing communication with a plurality of input/output devices via a network. The apparatus includes: a management unit configured to manage a communication session with the input/output devices; a storage unit configured to store information of the input/output devices in association with group information thereof; an execution unit configured to execute an application program; a communication unit configured to receive an operation instruction for the application program and to transmit to the input/output devices a processing result of the application program; a determination unit configured to determine whether the processing result requires connection of the input/output devices to an external server; and a message transmission unit configured to generate a message including an instruction to connect to the external server, when the determination unit determines that the processing results requires such a connection. The message includes the group information.

A determination determines permission/forbiddance to charge an accumulator that obtains electrical power from a power grid network. The determination device comprises a first acquisition unit configured to acquire first information about a requested power amount requested to charge the accumulator, a second acquisition unit configured to acquire second information about an available power amount that can be provided from the power grid network, and a determination unit configured to determine permission or forbiddance with respect to the accumulator based on the first information and the second information.
摘要:
A generation device generates a frame to be transmitted to a destination communication apparatus. The frame includes a first separation field, a first MAC protocol data unit (MPDU) following the first separation field, a second separation field following the first MPDU, a third separation field following the second separation field, and a third MPDU following the third separation field. The second separation field includes length information set to a value of zero to indicate no second MPDU directly follows the second separation field. The first MPDU includes a first MAC header, a first data field, and a first frame check sequence (FCS). The first FCS is for detecting an error occurred in at least the first data field. The third MPDU includes a third MAC header, a third data field, and a third FCS. The third FCS is for detecting an error occurred in at least the third data field.
摘要:
A communication apparatus includes a receiving device configured to receive one physical frame in which a plurality of MAC frames are aggregated. This physical frame includes one acknowledgement request frame for the plurality of MAC frames. The apparatus includes an acknowledgement frame forming device configured to form an acknowledgement frame representing reception statuses of the plurality of MAC frames in response to the acknowledgement request frame. The apparatus also includes a transmitting device configured to transmit the acknowledgement frame. This acknowledgement frame includes a compressed acknowledgement frame representing an acknowledgement bitmap having a size equal to a maximum number of MSDUs (MAC Service Data Units) when one MPDU (MAC Protocol Data Unit) corresponds to one MSDU.

An energy management apparatus includes: a communicator capable of communicating with at least a meter apparatus among the meter apparatus and a server apparatus that collects measurement information from the meter apparatus; a device registration processor configured to determine whether the direct communicator to the server apparatus can communicate with the server apparatus; if the direct communication is possible, transmit to the server apparatus a device registration message that requests to register a device identifier of the meter apparatus and a device identifier of the energy management apparatus; and, if the direct communication to the server apparatus is not possible, transmit the device registration message for the server apparatus to the meter apparatus; a communication processor configured to obtain energy control information of the device transmitted from the server apparatus; and a control executor configured to control the used energy amount of the device based on the energy control information.
摘要:
A physical frame is generated and transmitted to a destination terminal. In this physical frame, one of a data frame, an acknowledgement frame, and an acknowledgement request frame, and a transmission permission frame which is used in place of a normal Ack frame associated with a delayed Block Ack, and permits the destination terminal to perform piggyback transmission, are aggregated.
